The storm's snowy aftermath turned deadly for one New Jersey family when carbon monoxide from a blocked tailpipe killed a woman and her 1-year-old son and left her 3-year-old daughter in critical condition.

It happened while the children's father was steps away shoveling out the car, authorities said Sunday.

Sasha Bonilla, 23, and her two children had taken refuge from the chill inside the family's car on a New Jersey street while the kids' dad, Felix Bonilla, worked to clear the snow, Passaic Police said.
